**drwls**, Tuesday, December 21, 2010 at 10:20pmYou need to think it through and solve two equations. The fixture or chain that holds the chandelier exerts a tension force T upon it that is inclined 15.5 degrees to the vertical. The vertical component supports the weight, M g, and the horizontal component provides the centripetal force, M V^2/R . Thus

T cos15.5 = M g, and

T sin15.5 = M V^2/R

You can divide the last equation by the first to eliminate T and M

tan15.5 = V^2/(gR) = 0.2173

Solve for V, in m/s
